    Water has a tendency to find its way into most crawl spaces. That’s why you should not be surprised if you see water in your crawl space. But, how can you get rid of the water?

    Crawl spaces are an essential part of the home. They can be used for storage, cooling, and heating. Having a crawl space can give you a lot of benefits, but it is important to know how to properly remove water from your crawl space.

    Some people say that water is the one thing that is impossible to remove from a crawl space. But it turns out it’s not true. This article will teach you how to remove water from a crawl space without damaging or destroying the space itself.

    How to Pump Water Out Of Crawl Space

    1. Prevent More Water From Entering

    The first step is to isolate the leak and prevent more crawl space water from pooling as standing water under the house. Turn off all the water and find which pipe is causing the flooded crawl space!

    2. Drain With A Portable Sump Pump

    Next, you will need a portable sump pump. Place the sump pump at the base of the crawl space, run the drain hose into the yard and turn it on!

    Even a small crawl space sump pump will remove any standing water in about an hour (depending on the size of the crawl space). One thing to keep in mind is where you are draining the water – in some areas you can’t drain the water into your yard.

    Place the pump at the lowest part of the crawl space and let it run until all the water has been removed from the area.

    Superior Pump 91250

    If you do not own a portable sump pump we recommend the Superior Pump 91250. It is cheap, easy to use, and can be set up in almost any location in just a few minutes.

    3. Use A WetDry Vac and Dehumidifier to Remove Remaining Moisture

    A sump pump will remove most of the water but not 100%. A WetDry Shopvac and Dehumidifier will remove the remaining water so you don’t experience future mold problems. Make sure to use a vapor barrier and consider installing a crawl space dehumidifier to prevent long term problems from water damage.

    4. Install a Crawl Space Sump Pump and French Drain

    In some areas of the country your crawlspace will flood on a regular basis (just like your basement) and you will need to install a long term solution. Adding a sump pit and sump basin is the best way to prevent standing water, flooding and water damage.

    A crawl space drainage system is designed for a wet crawl space and draining excess moisture. A submersible sump pump will quickly drain any ground water via a drain pipe – just like it would in a flooded basement.
